A novel receiver window function for ICI reduction in OFDM system

Abstract

In this paper a novel receiver window function, for the reduction of Inter carrier Interference(ICI) in Orthogonal Frequency Division Multiplexing (OFDM) system, is proposed. The performance of the proposed window has been compared with raised-cosine (RC) window, better than raised-cosine (BTRC) window, rectangular window, and the modified bartlet hanning(MBH) window with reference to ICI and SIR. It has been observed that ICI power of the proposed window is 17.74 dB better than that of BTRC and 7.3 dB better than that of MBH window function at a normalized frequency offset of 0.05.
